Beta.freecodecamp.org signup error

Hi,
     I am not able to signup to beta.freecodecamp.org19. When I click on the link that I got in the mail, it says “oops something is not right, please request a fresh link to sign in/sign up”. I am trying from past 4 days,but every time I get the same error.



And will the progress of the challenges(not the projects) that I completed will be available on beta?




Please help.

Thanks!

I didn't find the right solution from the Internet.
